Unit-test-- ensure data is a particular number of hours.

Basically this issue falls into two parts.

First, make sure the hours limitation works. It has pretty predictable behavior:

(venv) daniel@mbp flagging % psql -d flagging

flagging=# select max(time), min(time) from hobolink;
         max         |         min         
---------------------+---------------------
 2021-02-07 09:40:00 | 2021-01-31 09:50:00
(1 row)

flagging=# select max(time), min(time) from usgs;
         max         |         min         
---------------------+---------------------
 2021-02-07 09:30:00 | 2021-01-31 09:00:00
(1 row)

flagging=# select max(time), min(time) from processed_data;
         max         |         min         
---------------------+---------------------
 2021-02-07 09:00:00 | 2021-01-31 10:00:00
(1 row)

flagging=# select max(time), min(time) from model_outputs;
         max         |         min         
---------------------+---------------------
 2021-02-07 09:00:00 | 2021-01-31 10:00:00
(1 row)

This is based on live data, not the mock data.

That's the second part of this issue. I currently have 1 test that uses live data, and the rest can use mock data. Am I doing a good job at isolating the two categories of tests? There might be a better way of doing this than what I'm currently doing. Need to look into that.
